Abstract

The invention discloses a method for configuring thermal power generating units to carry out self-healing of a power grid. The method comprises the following steps of: acquiring a network structure of the power grid and determining busbars in the network structure; respectively arranging a thermal power generating unit with a rapid voltage output function on each busbar, configuring different black start capacities for the arranged thermal power generating units, calculating the self-healing time of the power grid when different black start capacities are configured to each busbar after the thermal power generating unit is arranged, and determining the busbar and the black start capacity with shortest self-healing time; and arranging the thermal power generating unit on the busbar with the shortest self-healing time and configuring the black start capacity with the shortest self-healing time for the thermal power generating unit. Correspondingly, the invention also provides a system. According to the method and system disclosed by the invention, the positions of the thermal power generating units in the power grid network and the black start capacities needed to be configured for the thermal power generating units can be determined, and therefore the rapid self-healing capability of the power grid under the fault condition is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of grid self-healing in electric power systems, in particular to a method for configuring thermal power units to perform grid self-healing, and a system for configuring thermal power units to perform grid self-healing. Background technique [0002] The continuous expansion of the scale of the modern interconnected grid greatly improves the performance of the power system and meets the rapid development of the national economy. At the same time, due to the expansion of power supply scale, the loss caused by grid failure will be even greater. The power system is recognized as the most complex man-made system. As a network structure, local faults may induce chain reactions, leading to large-scale blackouts and even the collapse of the entire power grid. How to prevent large-scale power outages, realize the pre-control of potential system risks, and quickly recover after failures are major issues facing the ope...
